摘要

本文描述了一个新的测试调度问题,并给出了求解该问题的算法。当BIST(内置自检)结构集成在芯片上时,通过并行执行测试可以节省硬件开销和测试应用程序时间。通过将测试控制图和数据路径控制图合并为一个控制图,实现了控制信号位宽的减小和控制器的全局面积的减小。该控制图可以通过控制器综合系统CASTOR进行全局优化。

Test scheduling and controller synthesis in the CADDY-system
In this paper a new test schedule problem is described and an algorithm for its solution is presented. Hardware overhead and test application time is saved by executing tests in parallel, when BIST (built-in-self-test) structures are integrated on the chip. The authors achieve a reduction in the bit width of the control signals and the global area of the controller by merging the test control graph and the control graph for the data path into one control graph. This control graph can be globally optimized by the controller synthesis system CASTOR.<>
